exhaust blowing?

[Simonh]

ive had a new standard backbox fitted because it was blowing quite bad before and im sure its still doing it? how can i sort it out?

Maybe its not the backbox which is blowing?
Maybe it's somewhere else in the system.

how do i find out?

start it up and put your hand next to the exhaust to feel where it is leaking.

Take it to an exhaust place and most will check it free of charge.

Or jack the car up and have a look for any holes. If you do this with the car cold then run the engine you should be able to see, hear or feel any exhaust gases escaping without the exhaust being too hot to touch.

It may even be the flange where the backbox is fitted, maybe it was replaced without a gasket. Without someone looking at the car its impossible to say where its blowing.

cheers so which exhaust places do free checks?

Stick something in the end of the exhaust and you'll easily see / hear where the leak is

All places will check the exhaust for free, because they'l tell you which bit needs fixing. You can just say ahh i'l come back next week

Well if you're gonna get an exhaust fitted by someone, they will check it first. If they check it and see its fine, I doubt they will charge you for anything.

I wouldnt charge a penny for just looking at an exhaust for someone, would be like ripping someone off, but its fairly easy to do it urself if you want to, the rag in the end of the pipe is a good one, but if its bad you can usually tell just by getting down next to the car and having a listen
